The 1966 Indy 500 saw a chaotic opening lap following a collision between two cars at Turn 1 setting off a chain reaction that resulted in eleven cars retiring and the race being stopped for over an hour. The race restarted under a yellow flag. When the green was shown at lap 17, Mario Andretti took the lead but had a damaged engine and fell away immediately. Jim Clark then took the lead in his Lotus. After Jim Clarks spin, the race was between Lloyd Ruby’s Eagle and Jackie Stewart’s Lola until fuel stops put Clark temporarily back in front. Ruby was soon back in the lead but his car was black-flagged on lap 152 because the car was leaking oil. After Ruby’s retirement Stewart’s T90 was in comfortable lead, followed by Clark’s Lotus and Graham Hill’s T90. Hill had been quietly progressing up the field and at the lap 175 he passed Clark and moved to second place. Stewart continued to lead until a sudden lack of oil pressure forced the Scot to retire. Hill moved to the first place and just three and a half hours after the start Graham Hill and Lola won the 1966 Indianapolis 500.
